The MAC 300 operates under challenging conditions presented by heat, humidity, dust, and touring. Excessive dust,
grease, and smoke fluid buildup degrades performance and causes overheating and damage that is not covered by the
warranty. The fixture requires regular maintenance to keep performing at its peak. The schedule will depend on the
application and should be discussed with your Martin distributor. Refer any service that you are not qualified to per-
form to a professional technician.
Removing covers exposes dangerous live electrical circuits, hot surfaces, and a
lamp under high pressure. Procedures requiring the removal of any cover shall
be performed by professional users or technicians only. Disconnect the fixture

Use care when cleaning optical components. The surface on dichroic filters is achieved by means of special multi-layer
coatings and even small scratches may be visible. Residues from cleaning fluids can bake onto components and ruin
them.
1. Allow the components to cool completely.
2. Wash dirty lenses and filters with isopropyl alcohol. A generous amount of regular glass cleaner
may also be used, but no residues may remain.
3. Rinse with distilled water. Mixing the water with a small amount of wetting agent such as Kodak
Photoflo will help prevent streaking and spotting.
4. Dry with a clean, soft and lint-free cloth or blow dry with compressed air.
F a n s
To maintain adequate cooling it is important that the fans be cleaned of dust and dirt periodically. Use a soft brush, vac-
uum, or compressed air.
